January 2009 Meeting

Just a quick note to remind people that our next meeting is tomorrow night, Tuesday 27th January. Usual time and place.

I can't make this month, but Jeremy has kindly agreed to lead the session and provide a quick news update. Dennis is also pitching in with a quick presentation. So thanks to the guys for stepping in to at relatively short notice.

See you next time.

Chris.

Moon / Pleiades occultation

Unfortunately it was cloudy on the night of the 7th January 2009, when the moon/pleiades occultation occurred. As luck would have it, it was clear the following night...

So produced a montage based on individual frames of the moon and M45 taken on the 8th Jan but then merged them to show approximately what it would have looked like if it had been clear on the night before! Obviously the main flaws are in the exact position of the moon relative to the stars and the fact that the moon is 24 hours older. Never mind...




Single frame of moon taken at ISO100 with a 5 second exposure.
5 frames of M45 taken at ISO400 with a 5 second exposure. Aligned and stacked with ImagesPlus.
Moon and M45 images merged in Photoshop with position approximated to 1630hrs on 7th Jan 09.



13 frames of the moon taken at ISO100 with exposure time of 1/160th sec. Aligned, stacked and processed with RegistaxV4 .
3 frames of M45 taken at ISO400 with exposure time of 60 seconds. Aligned, stacked and DDP processing with ImagesPlus.
Moon and M45 images merged in Photoshop with position approximated to 1830hrs on 7th Jan 09.


The joys of trick photography.
